An insert panel assembly for the IDU cards at the hub of a point-to-multipoint millimeter wave wireless communication system. Generic cards with terminations for the selective connection of remote transceivers are provided with an apertured faceplate over which an insert panel may be placed to selectively block access to the card terminations. In one embodiment, the insert carries adaptors and another embodiment the connector on the conductor from the transceiver is configured to attach to the faceplate. In both embodiments the weight of the connector and conductor is supported by the chassis and not by the card. The connector is angled downwardly to avoid stress on the conductor and reduce the likelihood of kinking.
